摘要
影响交通安全的最主要自然因素是气象。针对公路气象分散采样的特点,介绍了一种嵌入式公路气象信息分布式采集系统。该系统采用模块化设计,运用了嵌入式技术,用CAN现场总线构建传感采集网络,以GPRS作为远程无线通信方案,并给出了软件设计程序流程。经过对系统的软硬件实验测试,验证了该系统设计的正确性和可靠性。
The main physical factor that affects traffic safety is weather. The text introduces the distributed acquisition system of embedded highway weather information according to the feature of discrete sampling of highway weather. The system used modularized design and embedded technology, constructed sensing collection network with CAN field bus and used GPRS as the long distance radio communication plan. The program flow of software design is provided. After experiment test of software and hardware of the system, the validity and reliability of the system is verified.
